Please keep the space before the #

Actually, I added the space before, but the when I use the tool 'scripts/checkpatch.pl' to check my format, it told me a warning that it should not have space.

The warning is as follow: WARNING: email address 'stable@vger.kernel.org #5.10' might be better as 'stable@vger.kernel.org#5.10'

Cc: stable@vger.kernel.org # 5.10

Should work.

I used 'scripts/checkpatch.pl' to check it, giving me the warning again.

The warning is as follow: WARNING: email address 'stable@vger.kernel.org # 5.10' might be better as 'stable@vger.kernel.org# 5.10'

And if I use the 'stable@vger.kernel.org# 5.10', warning too.

The warning is as follow: WARNING: email address 'stable@vger.kernel.org# 5.10' might be better as 'stable@vger.kernel.org#5.10'

It seems that the only non-warning format is 'stable@vger.kernel.org#5.10'.

Sincerely thanks, Jiang

The checkpatch.pl in 5.10.90 fails to parse the line as shown above. That is fixed in commit fccaebf00e60 ("checkpatch: improve email parsing") in the current tree.
